Personally, I do this kind of thing manually if I want to send some positive feedback to people who work at companies I like, but they don't have any obvious emails published. A recent example was the CEO of Evernote for the work put in to their behind the scenes series although I don't expect anyone to read it of course. People are busy! I wrote a bit about it here: https://utf9k.net/blog/email-lookup/ https://utf9k.net/blog/email-lookup/ Now does this scale? Not at all and I haven't read the email spec or anything like that. It's also handy in a pinch if you wrote down an email but can't remember if it's spelled correctly or not.
